Sherwin-Williams Macropoxy M905 (formerly known as Epigrip M905) is a low temperature curing, two pack epoxy high build undercoat, capable of curing down to 0°C.
Macropoxy M905 is used for application onto suitably primed surfaces, as an undercoat for use under suitable high performance finishes, where low temperature curing is required. It is also recommended for rapid overcoating and faster handling times.
Highways Agency Item No. 116
Network Rail Item Nos 7.1.7 and 7.2.2
Compatible with a wide range of epoxy primers, whereby Macropoxy M902 Winterfast Hi-Build Brushing Aluminium is the preferred primer.
For overcoating with epoxy products (including self overcoating), the maximum recommended interval is 28 days at 23°C. For overcoating outside this interval, consult Sherwin-Williams technical support for advice.
Where a high degree of gloss and colour retention is required overcoat with Acrolon C137V2, Acrolon C237, Acrolon 1850 and Acrolon 7300 within 7 days at a minimum dft of 50 microns or in the case of Acrolon C750V2 overcoat within 4 days. These overcoating times refer to achievement of optimum adhesion at 23°C and will vary with temperature.
For overcoating with alkyd systems consult Technical Team for advice.
Application Conditions & Overcoating
In conditions of high relative humidity, ie 80-85% good ventilation conditions are essential. Substrate temperature shall be at least 3°C above the dew point and always above 0°C.
Application at ambient air temperatures below 5°C is not recommended where there is a risk of ice formation on the substrate.
Due to the high solids content of this material, it is not normally possible to achieve at dry film thicknesses much less than 100 microns by brush application.
Development of satisfactory physical properties including hardness and abrasion resistance will be obtained within 24-48 hours at a temperature of 5°C. Optimum water and chemical resistance will be achieved when the material is fully cured.
If it is desired to overcoat outside the times stated on the data sheet, please seek advice of Technical Team.
